When Beatrice gets a frantic call in the middle of Sunday Lunch in New York to tell her that her younger sister Tess is missing, she gets onto the next flight to London.

When Tess turns up dead in a toilet block in Hyde Park, her body is sent off for testing. When the results come back it suggests that Tess committed suicide and everyone accepts that - everyone except Beatrice. Beatrice knows that Tess would never take her own life, not after their brother Leo had died from an illness called Cystic Fibrosis. Beatrice thinks that her sister was murdered and embarks on a mission to find out by whom.

Sister is an AMAZING book! I really loved it! Although it had a few complicated bits in it because it's for older readers there weren't that many bits that confused me, I understood most of it in the end.

Sister isn't one of those books where you have two suspects that could be the people who committed the murder; in Sister any one of the characters could be responsible for Tess's death.

I think you were always with Beatrice in all of her suspicion's; she would think it was one person and then she would discover more clues and then she would change her mind and start finding someone else more suspicious than the previous person, but you are always with her. Every time she changes her mind on who the suspect is so do you.

I was never 100% certain who I thought the murderer might be.

I did seem to stop being 'into it' for a few chapters slightly closer to the end because it got a bit boring - there weren't any new clues discovered - and then there were and I was instantly engrossed in it again!

Sister is written in a way that I've never read before: as a letter. A letter Beatrice is writing to Tess even though Beatrice knows Tess is dead. And it's also told as Beatrice is telling her Shrink her story and Tess's. At the very end it's all about who actually did murder Tess and that gets you hooked! You're desperate by this time after all the clues, all the things that have made you suspect this person and made you suspect that person, you are finally ready to know who did it!

Whoever it was it was going to surprise me because there are just so many characters that could possibly be the murderer but I had to say when I found out who the murder was I actually gasped in shock! I was not expecting it at all!

There are a lot of unexpected things that happen closer to the end and throughout the entire book actually; I love how the story unravels bit by bit, it gets you more engrossed than any book ever has before!

I'm generally a really fast reader but at the end of Sister I took longer to finish it than I possibly ever have before because I kept having to go back and re-reading bits to check I had read it right!

I really love Sister! I think if you're a big fan of mystery and crime fiction books you should definitely 100% read this book! Even it you're not a fan of those things you should read this book!

Over 5 stars definitely! 13+
